The development of a high precision record of atmospheric radiocarbon shifts beyond 14,000 calendar years BP—obtained through combined studies (e.g., dendrochronology, radiocarbon dating and comparisons with other radionuclide records)—represents a crucial improvement within the widely applied radiocarbon dating method, allowing more accurate dating of sub-fossil samples and hence, establishing the chronology of past environmental and climate changes during glacial times.
